Abstract
A cable includes a structural core and an outer layer having glow-in-the-dark properties. In an advantageous embodiment, there is provided a cable of coaxially laminated structure, which includes a structural core, an inner layer surrounding the structural core, and an outer layer, or “skin”, surrounding the inner layer and having glow-in-the-dark properties. The inner layer presents a light colored or reflective outer surface such that a major portion of incident light striking the surface is reflected back.
